Silver Chloride (AgCl) |
| Silver Chloride is a useful material for deep IR applications where sensitivity to moisture is a problem. This soft crystal deforms under heat and pressure and can be forged in polished dies to create IR windows and lenses. A major use for Silver Chloride is in the manufacture of small disposable cell windows for spectroscopy, known as mini-cells. These windows have a depression of controlled thickness pressed into the surface. The inherent cost of Silver Chloride material is offset against ease of manufacture. |

Product Notes |
Silver Chloride is grown into small ingots by the sealed-ampoule Stockbarger techniques. Silver chloride is malleable and milky-white it darkens in sunlight, but mild darkening does not affect the IR performance.
